DOOR CLOSER AND CHECK.

Specification of Letters Patent.

Patented July 17, 1906.

Application filed April 3, 1905. Serial No. 253,593.

To all whmn it ntay concern.-

Be it known that I, CARL H. STEMPEL, a citizen of the United States, residing at Fort Madison, in the county of Lee and State of Iowa, have invented certain new and useful Improvements in Door Closers and Checks; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in door closers and checks and it consists in certain novel features of construction, combination, and arrangement of devices hereinafter described and claimed.

The object of the invention is to provide a simple and inexpensive mechanism of this character which is well adapted for the purpose intended and which may be readily applied to screen-doors and the like.

The above and other objects, which will appear as the nature of my invention is better understood, are accomplished by means of the construction illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a portion of a screen-door, showing the application of the door closer and check thereto. Fig. 2 is a horizontal sectional view taken through the door, showing the same closed and also show ing the door closer and check attached to the door. Fig. 3 is a horizontal sectional view, the door being in its open position; and Fig. 4 is a detail sectional view through the door closer and check on an enlarged scale.

A portion of a door-frame is indicated at 1, and 2 represents a screen door, which is hinged at one side of the door-frame, as at 3.

The purpose of my invention is to close the door after the same has been opened and prevent a door from slamming while being closed.

A rod 9 passes through a coiled retractile spring 17, one end of which is adjustably secured to the rod near the corresponding end thereof by engaging screw-threads 18 on said. rod. Said end of the rod is formed with a hook 10, which enters an opening in a lug 11 to pivotally connect the rod to the lug. The lug operates in a slot 14 in a bracket 12, which is screwed or otherwise secured on the door 2. The inner end of the lug has lateral extensions 16, provided with corrugations which engage similarcorrugations on the inher side of the bracket, so that said lug will be securely held in place, but may be adjusted by first loosening or removing the bracket, as will be understood. The other end of the rod is beveled on one side, as at 20, and has a notch 21 on the opposite side. The rod passes through and is longitudinally movable in a guide in a casing 6, the end of the spring opposite that which is adjustably secured on the rod being secured to the said guide. In the casing is a check or stop 19, pivoted near one end, as at 24, notched near said end on its under side, as at 26, and provided at said end on the opposite side with a cam 23. The other end of the check or stop has a hook 22. A spring 25, secured to the casing, is adapted to bear in the notch 26 to normally dispose the hooked end 22 of the check or stop in a depressed position out of the path of the rod. Said spring is also adapted when the hooked end 22 of the stop is in an elevated position to engage the inner end of said stop to hold it in such position.

The casing is pivotally connected, as at 27, between the ears of a bracket 28, secured to one end of a V-shaped buffer-spring 29, the other end of which is secured, as at 30, to one j amb of the door-frame 1. When the door is opened, which is done against the tension of the spring 17, the rod 9 is drawn outwardly from the stop or check 19 and the guide 7, and as it passes over the stop engages the cam 23 thereof and turns the stop so that its hooked end 22 is elevated, the spring 25 by engaging the inner end of the stop maintaining the latter in such elevated position. When the door is released, the spring 17 moves it toward a closed position, the rod 9 striking the hooked end 22 of the stop before the door is entirely closed and preventing the door from slamming. The spring-bracket 29 acts as a cushion, and the force of the impact of the rod against the hooked end 22 of the stop causes the door to rebound somewhat and the rod 9 partakes of such 1novement,whereupon the spring 25 by engagement with the notched portion 26 of the stop depresses the hooked end of the stop and the rod and then passes over without engaging such hooked end of the stop, while the spring 17, being nearly spent, completes the closing of the door, which it does without slamming the same.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A door closer and check comprising a spring to close a door, a stop connected to the jamb, an element connected to and movable with the door to engage the stop before the door reaches an entirely-closed position and cause the door to rebound, and a spring bearing against the stop, eflective during the rebound of the door to move the stop out of the path of such movable element, to enable the spring to complete the closing of the door, said stop and said movable element having coacting devices to set the stop in engaging position when the door is opened.

2. A door closer and check comprising a spring to close a door, a rod connected to and movable With the door, a guide for the rod connected to the jamb, and pivoted stop mounted on said guide having a hook to engage the red when the door is partly closed and further provided with a cam to coact With the rod when the door is opened, to turn the step into engaging position.

3. A door closer and check comprising a casing, a spring connecting the casing to the door-jamb, a rod having a spring connection With the casing and guided thereby, means for adjustably securing one end of said rod to a door, a stop in said casing to engage the rod before the door reaches an entirely-closed position, and a spring also in the casing, bearing against the stop and effective during the rebound of the door to move the stop out of the path of the rod and enable the spring connecting the rod with the casing to complete the closing of the door, said stop and said rod having coacting devices to set the stop in en gaging position when the door is opened.

4. A door closer and check comprising a rod having one end connected to a door, a door-closing spring coiled on and attached to said rod, a casing forming a guide for the rod and to Which said door-closing spring is also attached, a connection between said casing and the door-jamb, a stop in said casing to engage the said rod before the door reaches an entirely-closed position, and a spring also in the casing, bearing against the stop, effectlve. during the rebound of the door to move having a hook 22 to engege the end of the rod and arrest the door before the latter reaches an entirely-closed position, and also having the hook 23 and a spring connected to the guide and bearing against the stop to disengage the hook 22 from the rod during the rebound of the latter With the door, to permit the entire closing of the door and set the hook 23 of the stop in position to be engaged by the notched portion of the rod to restore the stop to its initial position When the door 1s opened.

6. A door closer and check comprising a rod, a slotted bracket formed with corrugations and adapted to be secured upon a door, a lug pivotally attached to one end of the rod, adjustably mounted in the slot of the bracket and adapted to be adjustably engaged With the corrugations thereof, a guide for said rod, a door-closing spring connecting said guide and rod, means to connect the guide to a door-jamb, a stop pivotallymounted in the guide and having the hooks 22 and 23, and the spring 25 secured to the guide and bearing against the door-stop, the said rod having the notch 21. in the side neXt the stop and near the free end of said rod, substantially as described.

In testimony whereof I have hereunto set my hand in presence of tWo subscribing Witnesses.
